Bitscope - FM MODULATION EXAMPLE

[darkspeed]

I find this feature really useful on my bitscope..

I'm impressed the product line includes a signal/timing gerator add on.

One unit that both generates AND displays/captures the variations in circuit,
and all that can be controlled by a PC for tight control and data logging?

Wow, whats not to like...

The whole thing is open source

PARTS LIST : http://www.bitscope.com/design/parts/

and you can write custom virtual meters for it http://www.bitscope.com/design/manual/

They have ported their DSO software to Unix and are going to release a MacOSX port soon..

I have a network version of the 325 and I really like it!

Now see, this is the way all things should be. 

Sadly, it reminds me of a much younger definition of "Open Source"
when I was hand wire-wrapping 8-bit Z80 boards by myself
to do what the $0.40 PIC's now do on a PC screen.

No one made what I wanted,
I had no choice but to make it myself...

And when they named it "Basic" back then,
it really was BASIC (Acronym joke).

Oooops, showing my age with that one aren't I?

Ok this has reached an all new level of cool!

BitScope WaveMeter | Automated Waveform Analysis
Designed to be used stand-alone or as a partner application for BitScope DSO, WaveMeter is a fast and easy to use AC/DC voltmeter and auto-locking frequency meter with a built-in oscilloscope for live waveform display.

Simply connect a signal and WaveMeter will lock on and display the waveform while simultaneously reporting the frequency, Peak, RMS, Min/Max and DC voltages.

In contrast WaveMeter employs a powerful autocorrelation detector which can lock on to different frequencies in the one signal and even find frequencies in a waveform which is not obviously periodic.

Free program - support 8/16/24 bit soundcard

http://www.sillanumsoft.org/

VA is a real time program which simulates a set of electronic instruments, such as:

- Oscilloscope (dual channel, xy, time division, trigger);
- Spectrum Analyzer with amplitude and phase display (linear, log, lines, bar, octaves band analysis 1/3, 1/6, 1/9, 1/12, 1/24);
- Wave-form generator with "custom functions", triangular, square, sinusoidal (all with NO ALIASING and smooth transition), white/pink noise, pulse generation, DC generation[New!];
- Frequency meter (in time and frequency domain) and counter; in time domain by means of a real time zero crossing algorithm;
- Volt meter with DC[New!], true RMS, peak to peak and mean display plus resolution calculus;
- Filtering (low pass, hi pass, band pass, band reject, notch, "diode", DC removal);
- Memo windows (data log) for analysis and storage of time series, spectrum and phase  with "triggering" events; THD and Impedance data logging with spline interpolation; possibility to save the graphics in various format (.tee, .txt, .wmf) )and display them with an internal viewer[New!];
- Screenshot of Spectrum and Scope window;
- A TRUE software digital analog conversion (for complete signal reconstruction using Nyquist theorem) ;
- Frequency compensation: possibility to create/edit a custom frequency response and  add it to the spectrum analyzer computed spectrum; added standard weighting curves A,B,C [New!]in parallel with custom frequency response;
- Support for 8/16/24 bit soundcard by means of API calls;
- Internal 80 bit IEEE floating point variables for minimum rounding error;
- Unlimited frequency sampling (depend from the capabilities of your soundcard/acquisition device);
- Cepstrum analysis;
- Cross Correlation;
- Extended THD measurements, with automatic sweep, compensation, data log;
- ZRLC-meter with Vector scope, automatic sweep in time and frequency for automatic measurement;[New!]
- Calibration mechanism (you can calibrate the VA scales directly in VOLT or dB or percent full scale) ;
- Set of values computed in real time (peak to peak, peak, crest factor, form factor, true rms, mean, frequency with zero-crossing algorithm).[New!]

Looks nice Wings.

DL'd for review later,
and shot him an E-Mail offering to help for free
with his english translation efforts too.

Nice find.
